I appreciate requests for enhancement should be made by raising a ticket but I have seen possible changes discussed in the forum and an impression gained as to whether the proposal is possible and can be accomplished with relative ease.

I can see circumstances where I would like to place books in a series to keep them together but without any numbering. An example would be the plays of Shakespeare.

I would like a button on the individual edit metadata screen and indeed the edit bulk metadata alongside the number field opting for no brackets and no number in the screenview for that/those books. It could perhaps be a toggle so the decision could be reversed later if desired.

I wonder if anyone else supports this idea

Make a Tag [The Bards works], no need to misuse "Series"
To do bulk <anything>, simply set the filter to the tag(s) you want
